Sorry - I don't actually have a cat at all - I was just hoping someone would come back with "DUH - all cats bury their @@@p" So's I could come back with "Not with a bloody shovel they don't!"
We did have a cat though, my wife left the animal sanctuary that she used to run with him, plus 3 Irish wolfhounds! But we have a very large garden, with fields and woods beyond and the cat had a special toilet area in the garden. He hardly ever ventured out front of the house, maybe for the odd scrap!
Cats are indeed free spirits but if the owner provides an area more attractive to them than a neighbour's garden, they'll use it, and if the garden is large enough then maybe it'll be all the 'territory' it needs as well, so won't need to go spraying areas outside of it.
Even if there is no garden at all there are still things that can be done - like don't allow the cat out until it's used the litter tray - it'll get used to it.
If there is no owner i.e. the cat is wild or a stray there are cat protection league type organisations that will relocate/neuter the feral ones or home the strays. If there is an owner, s/he is responsible.
I'll see if my wife has any tips/knows why the bottles work - what she doesn't know about cats you can fit in your garden!
